Sick of doing valve adjustments yet? You’re not alone. Pick up a Steel Intake Valve Kit from Pro X for some valves that will last a seriously long time without giving up any performance.

Pro X manufactures these exhaust valves so close to OEM specs you can reuse the same retainers, bases, and seals without any modifications. It all begins with a 21-4N stainless steel valve that is black nitrided for an unprecedented combination of core strength and surface friction reduction. Then comes the chrome vanadium, heavy duty springs built specifically to handle the extra weight of steel valves. Even at high rpms these springs hold a tight seal so your valves won’t flutter or float even after seasons of being heavy on the throttle.

Experience what it’s like to spend your time riding instead of checking clearances with a premium set of components in the Pro X Steel Intake Valve and Spring Kit.
